Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20662, here are decompositions:
- 23 + 20639 = 20662
- 113 + 20549 = 20662
- 179 + 20483 = 20662
- 251 + 20411 = 20662
- 263 + 20399 = 20662
- 269 + 20393 = 20662
- 293 + 20369 = 20662
- 401 + 20261 = 20662
Showing the first eight; more decompositions exist.
